data-custom-properties not picked up if option is inside an optgroup

[powerbuoy]

I've been using <option data-custom-properties="somevalue"> on my multiple select to store some additional data I need. This has been working fine until today when I wrapped my <option>s in an <optgroup>. Suddenly all my customProperties are null. This looks like a bug to me?

Dirty fix for this one is find the var addGroupChoices = function (choice) { ... change the customPropeties: choice.customProperties in to customProperties: choice.getAttribute('data-custom-properties'),
